People can be as crazy as they want to be. William Spengler set his home ablaze and killed the first respondents on the scene. The pistol that he used was similar to the one used in the killings of Sandy Hook Elementary, a Bushmaster .223 caliber rifle. “I still have to get ready and see how much of the neighborhood I can burn down, and do what I like doing best, killing people,” Spengler left in a note. I pray for crazy of this caliber. Drop down bottom for more.
